supervision and construction of geotechnical engineering works such as land
reclamation, earth (soil and rock) works, ground improvement works, foundations

geotechnical data collected during the progress of site works, and after
completion of the works.
14. Assist the
Client General Managers and Project
Managers in promoting and developing the geotechnical knowledge within the Client,
which shall include meeting with potential Developers, Purchasers, Contractors,
and Consulting Engineers, and making technical presentations.
II.LIST OF
SERVICES TO PREVIOUS CLIENTS :( e.g, NAKHEEL, EMAAR, ALDAR and Other Past Clients):
i)
Expert advise/consultancy, analysis, design
and supervision of geotechnical aspects of dredging, land reclamation, shoring
protection, earth fill, foundation, and offshore works.
ii) Establishment
of terms of reference for geotechnical investigation studies (field and lab
testing) required for ensuring safe and economic design and durable
construction of land reclamation works, buildings and infrastructure
development on rock and soil.
iii) Evaluate and
interpret results of geotechnical site and lab investigations, and make
recommendations on: i) suitability of
project site and most appropriate type of foundation considering structure,
ground conditions and cost and time constraints, ii) requirement of ground
improvement, and stabilization measures to ensure achieving targeted level of safety, and iii) rock/soil material
engineering design parameters for geotechnical works.
iv) Develop
quality control procedures (sampling technique, field and lab testing, verification procedure, etc) to ensure
delivery of geotechnical material (e.g.
rock armour quarry run, filter material, dredged and land fill material, etc)
in full compliance with targeted specifications and standards.
v) Establish design
criteria and conduct analysis and design of geotechnical works dealing with
soil and rock material (e.g. shallow and deep (piling) foundations, ground
improvement works, diaphragm walls, embankments, shoring protection works,
earth and retaining structures, underground excavation support works, tunnels,
ground water control system, etc).
vi) Develop
earthquake design parameters and response spectrum for design of buildings and
infrastructure considering regional tectonics and local geology and soil/rock conditions.
vii) Develop a
workable investigation plan for selecting best dredging material and dredging
sites for use in land reclamation for upcoming Client projects to ensure full
compliance with targeted specifications and avoid problems of liquefaction, excessive
fines content, weak materials, piping erosion, creep settlement, and other
durability related problems. Evaluation of properties of dredged material based
on such studies and make recommendations.
viii) Recommend
best practices for land reclamation works and most effective methods of ground
improvement works for each type of dredging material ensuring compliance with
safety and design requirements (settlement, bearing capacity and resistance to
liquefaction), cost requirements and optimum time of execution.
